Jindal spiral welded pipes (SWP) are made from a strip of low carbon structural steel or low alloy structural steel that is rolled into a tube blank at a specific spiral angle and then welded together. It's possible to make it with a thinner strip. Steel is used to manufacture large-diameter steel pipes. Its specifications are specified as outer diameter * wall thickness, and the hydraulic test, weld tensile strength, and cold bending performance of the spiral welded pipes must all meet the criteria.
